Abstract
Imaging devices, systems, and methods are provided. Some embodiments of the present disclosure are particularly directed to imaging a region of interest in tissue with photoacoustic and ultrasound modalities. In some embodiments, a medical sensing system (100) includes a measurement apparatus (102) configured to be placed within a vascular pathway. The measurement apparatus may include a sensor array (106) comprising two or more sensor modalities. The sensor array may be configured to receive sound waves created by the interaction between emitted optical pulses and tissue, transmit and receive ultrasound signals, and rotate around a longitudinal axis of the measurement device. The medical sensing system may also include a processing engine operable to produce images of the region of interest and a display configured to visually display the image of the region of interest.
